Vermont Gage 111236800 Class Zz Minus Plug Pin Gage 0.3680 in

Product Description

The VERMONT GAGE 111236800 is a Class ZZ Minus plug pin gage machined to a 0.3680-inch diameter with a tolerance of 0.0002 inches. Designed for NoGo inspection duty, this pin gage is used to verify that a drilled, reamed, or bored hole does not exceed its maximum allowable size. The steel construction holds the tight dimensional tolerance required for reliable go/nogo gauging in production and quality-control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO and AS9100 quality systems. The 2-inch overall length suits standard pin gage handles and collet-style holders commonly found in machine shops and inspection labs.

This pin gage is suited for inspection of machined bores, drilled holes, and precision-fit features in residential, commercial, and industrial manufacturing settings. Typical applications include verifying hole sizes before press-fit assembly, checking reamed bores on CNC-machined components, and calibrating or verifying the setup of micrometers, verniers, and other measuring devices. The 10 microfinish surface finish minimizes gage wear and reduces measurement uncertainty during repeated insertions. Machinists, quality technicians, and tool-and-die professionals are the primary users.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo hole inspection
• 0.3680-inch diameter, 2-inch overall length fits standard pin gage handles
• Steel construction for durability and dimensional stability
• 10 microfinish surface for reduced wear and consistent measurement
• Includes Certificate of Accuracy with NIST Traceability
• Suitable for setting and verifying micrometers, verniers, and other measuring devices

Compatibility

Designed as a NoGo plug pin gage for use with standard pin gage handles and collet holders; also serves as a setting reference for micrometers, verniers, and other precision measuring devices where a 0.3680-inch reference diameter is required.

Installation Notes

Pin gages are handled by quality technicians and machinists and require no installation in the traditional sense. Store the gage in its protective case when not in use to prevent nicks, corrosion, and dimensional change. Clean the gage and the part bore with a lint-free cloth before inspection to avoid false readings caused by chips or coolant. Never force a pin gage into a hole; if resistance is felt, the hole is at or below the NoGo limit.
